What happens when you search for two ASCII words separated by space?
``` C:\Program Files (x86)\Geany\bin>echo Without name > "c:\666\example2.txt"
C:\Program Files (x86)\Geany\bin>grep -nHIiFR Without name C:\666 /Geany/bin/grep: name: No such file or directory C:\666/777/example.txt:4:Without name C:\666/example2.txt:1:Without name
C:\Program Files (x86)\Geany\bin>grep -nHIiFR "Without name" C:\666 C:\666/777/example.txt:4:Without name C:\666/example2.txt:1:Without name
C:\Program Files (x86)\Geany\bin>copy "c:\666\example2.txt" con Without name 1 file(s) copied.
C:\Program Files (x86)\Geany\bin> ``` With ASCII symbols it works as expected even with enclosing.
